What has caused my RT eyebrow & eyelid to drop?Why does it seem that my R eye has sunk into the socket appearing smaller?(photo)

On the other hand, you clearly have upper eyelid ptosis.  This is worse on the left eye and there is a stronger left brow compensatory elevation making the right brow look like it has fallen.  You need an consultation with an oculoplastic surgeon to assess the upper eyelid ptosis and determine the best option for correcting it.

You did a nice job of posting photos from when things were apparently normal and now: this is very useful if you want to get guidance worth something.1. If your eye has truly sunken in, this will certainly make your upper lid and the brow seem heavier as there is no longer the mechanical support to these two when this happens. A number of conditions can cause this. A clinical examination would look for specific signs.2. I can't make out your pupils, but some young people can get a condition that will change the size of your pupil and give you a droopy upper lid.3. If your right side of the face has always been smaller than the left (asymmetry is universal in us all!), then it is possible that the heavier  brow and upper eyelid have just become more noticeable with no underlying disease or condition. However, if you can accurately pinpoint to an acute change, then a specific cause would be looked for.You would need a clinical examination which will yield a lot. An X-ray may or may not be necessary. Whereas many specialists can perform many procedures, for a diagnosis such as yours, you want to see either a near-ophthalmologist or an orbitally trained surgeon, who will also have expertise in diseases or conditions of the eyelids and brows. There are several excellent surgeons in Alabama who can see you. If you need a name, email us and we will be happy to provide you with a couple of names.Good luck.Prof. Bhupendra C. K.

Anytime the eyebrows are at a different level, the eyelids will appear different. The further down the brow is, the more crowded the eyelid on that side appears. Most people have at least a slight difference in the level of the eyebrows. The cause can be simply that you sleep on one side more than the other causing downward pressure on the brow. Muscle or nerve weakness from any cause can allow one brow to droop more than the other. Enough trauma to the cheek that causes bruising of  the nerve or swelling of the cheek over the lateral cheek bone can cause the nerve not to be as strong. Neurotoxins such as Botox or Dysport can relax the muscles more on one side than the other. Eyelid ptosis (droopy eyelid) more on one side than the other can cause the brain to compensate by elevating one brow more than the other, but this is often associated with a higher lid crease on that side as well. With the sudden change in lid height, consultation with an ophthalmologist or oculoplastic surgeon is recommended to determine the cause, before cosmetic correction is performed.John Standefer MD
